Stage6 Sport Pro Clutch.
Sport Pro series clutch by Stage6. The 3-shoe clutch can be adjusted by 2 lock-in positions and by choosing different clutch springs. Clutch shoes and retainer ring are reinforced, everything is held in place by screw-in bolts (not simple rivets with a tendency to get loose).
This part is designed for use with 50/70cc sport to mid race engines. Better take-offs, longer lifespan, fair price - this clutch kit is definitely on our favourites list. For racing and high-end engines, we recommend the Torque Control by Stage6.
d = 107mm.
Attention: Minarelli engines started being equipped with different clutches in 1998. Please check if you need a 2-shoe (d = 105mm) or a 3-shoe (d = 107mm) clutch; you can also measure the inner diameter of the bell to find out what type you need.
Note: we recommend to use the spring seat (included) for the torque spring for Minarelli engines only (Aerox, Booster, Chinese scooters etc.). It is not recommended or necessary for Peugeot, Piaggio and GY6 4-stroke engines.
This clutch uses a 107mm clutch bell and will work with the 3 spring clutches.
107mm bell is available here
